Specific embodiment
The technical solution of the utility model is described further below in conjunction with attached drawing.
As shown in Figures 1 to 7, in the engine cylinder cover of the utility model point positioning fixture include bottom plate 1, positioning device 2,
Pressing device 3, fixed pin 4, Auxiliary support 5, the positioning device of setting on one side 2 of bottom plate 1, pressing device 3 is arranged in excess-three side, fixed
Fixed pin 4 is arranged in 3 two sides of pressing device on position 2 opposite of device, and Auxiliary support 5, cylinder cap to be processed is arranged in 2 side of positioning device
6 are placed within 3 area defined of positioning device 2 and pressing device, as shown in Figure 7.
As shown in Figures 2 and 3, the positioning device 2 of the utility model is fixed including swingle 21, the first fixed station 22, arc
Potential head 23, extension spring 24, locating clip 25, the second fixed station 26, clamping head 27, connecting shaft 28, the first fixed station 22 and second
Fixed station 26 is fixedly connected on bottom plate 1.Second fixed station 26 connects two locating clips 25 by connecting shaft 28, makes locating clip 25
Two sides can be rotated along connecting shaft 28, and 25 one end of locating clip is connected on the second fixed station 26 by extension spring 24, locating clip 25
The other end inside clamping head 27 is set.Swingle 21 is set on first fixed station 22, is positioned on front side of swingle 21 for arc
First 23, swingle 21 rotates forward, and arc positioning head 23 is gradually inserted into the gap between two locating clips 25, keeps locating clip 25 another
The clamping head 27 of side inwardly clamps, and realizes the clamping for treating processing cylinder cap 6.After completing processing, 21 back rotation of swingle, arc
Shape positioning head 23 moves away from the gap between two locating clips 25, and under the pulling force of two sides extension spring 24, clamping head 27 is outside
It gradually separates, cylinder cap 6 can be taken off.The effect of the utility model positioning device 2 is the process inwardly clamped by two clamping heads 27,
It realizes the accurate positioning and clamping for treating processing cylinder cap 6, keeps positioning operation simple and convenient.And the utility model is fixed by arc
